My prediction is that Pakistan will win the toss, bat, and be 2 for 60 at lunch.
Pakistan have played thirty-two Tests in Australia, have won only four, two of which were during World Series Cricket, and won only one in the last thirty-five years. (They had good chances to win in Sydney in 1973 and Sydney in 2010 during the Summer of Kidding Ourselves, but blew both Tests.) Hardly a record that suggests they are comfortable playing in Australia. Nevertheless, if Pakistan get the rub of the conditions they could be hard to beat, especially if Barmy Amir gets the pink pill hooping at night. But my peer-reviewed gut-feeling is that Australia will win the series.
The good old ODI. I've said it before, but it warrants repeating: dumping the ODI in favour of T20 - mooted by idiots like me - is stupid. ODIs, even if the Aussies treat them as practice matches, are relaxing and entertaining Sunday afternoon fare.
